Definitions
- This invention relates generally to hydraulic systems for internal combustion engines. More particularly, this invention relates to hydraulic stems having a combination filter screen and gasket to remove debris from the hydraulic fluid in a fuel injection system with a high-pressure pump and a priming reservoir.
- metal chips and other debris may remain in the engine even when engine parts are cleaned prior to assembly.
- fittings with tapered thread connections create metal chips when assembled into a threaded hole. Machining also may leave metal chips. Casting processes may leave other debris in core passages and crevices. As a result, engines inevitably have some debris inside deep-drilled holes, cast-in core passages, and other places. During engine operation, the heating and cooling of the engine releases this debris into the hydraulic fluid. As the hydraulic fluid flows, the metal chips and other debris move throughout the hydraulic system.
- a priming reservoir typically is disposed at a level higher than the inlet to the high-pressure pump.
- the priming reservoir includes a lower reservoir portion usually cast into the engine front cover. An upper reservoir portion is attached to the lower reservoir portion to increase the reservoir volume. A gasket seals the lower and upper reservoir portions.
- the priming reservoir provides gravity feed to the pump during engine start-up. Any debris in the hydraulic fluid tends to accumulate in the priming reservoir. On engine start-up, the pump drives accumulated debris throughout the hydraulic system. While the engine is running the pump continues to drive debris through the hydraulic system.
- Debris in the hydraulic fluid may obstruct sensors, valves, and other parts of the hydraulic system and, especially, the hydraulic-actuating portion of the fuel injector system.
- Metal chips may clog injector pressure regulators, high-pressure pumps, injectors, and pressure control valves because these parts typically are manufactured to very close tolerances. Even though some parts (e.g., the pressure control valve) have internal filters (e.g., an edge filter), too much debris may clog and prevent proper function of these filters.
- the present invention provides a hydraulic system with a combined filter screen and gasket--a filter gasket--for removing debris from hydraulic fluid in an internal combustion engine.
- the filter gasket also seals the upper and lower reservoirs to form a priming reservoir for the hydraulic system.
- an upper reservoir structure is mounted on a front cover at an interface.
- the front cover forms the lower reservoir and has a top edge with a depression.
- the upper reservoir structure forms the upper reservoir and has a bottom edge.
- the top and bottom edges form the interface.
- the filter gasket is located at the interface and has a gasket and a screen assembly.
- the gasket is located along the interface inside the depression for sealing the upper reservoir structure to the front cover.
- the depression's depth and the gasket's thickness control the "squeeze" on the gasket.
- the screen assembly has a plate member located at the interface for connecting with the gasket.
- the plate member forms an aperture having a cross-section area.
- a filter screen is connected to the plate member for enclosing the aperture.
- the plate member is integrally connected to the gasket.
- the plate member has bonding holes along its periphery.
- the gasket material fills the bonding holes to mechanically connect the gasket to the plate member.
- the edges of the plate member may be treated with a bonding agent to chemically bond the gasket to the plate member.
- the plate member is not integrally connected to the gasket.
- the loose gasket is placed in the depression at the top edge of the front cover.
- the plate member is positioned inside the gasket and between the upper reservoir structure and the front cover.
- the plate member is thinner than the depth of the depression, but extends to contact the gasket along its periphery.
- the plate member separates the upper and lower reservoirs, forcing the hydraulic fluid to pass through the filter screen.
- the filter screen retains any debris in the hydraulic fluid larger than the filter screen's mesh size.
- the filter screen has an open area large enough to provide the desired pressure drop for operation of the pump. Consequently, the filter screen may have a surface area larger than the cross-section area of the aperture. If so, the filter screen has an open end and a closed end. As shown, the filter screen has a cylindrical shape. However, it may have other shapes including conic, rectangular, or flat. In addition, the filter screen has a mesh size to retain particles large enough to cause damage to the hydraulic system or other parts.
- the screen assembly may have a flange for connecting the filter screen to the plate member. A flange would facilitate producing a solid weld for joining the filter screen to the plate member.
- the plate member may have a basket assembly.
- the basket assembly mechanically supports and may be connected to the filter screen.
- the basket assembly, the plate member, and the filter screen may be a single part. While the screen assembly may be made from other materials and combinations of materials, the basket assembly is preferred when the screen assembly is made of plastic.

- FIG. 1 shows an internal combustion engine 10 having a V-configuration.
- the engine 10 has a hydraulically actuated electronically controlled unit injection (HEUI) fuel system including a priming reservoir.
- the engine 10 has an upper reservoir structure 30 mounted on a front cover 14 at an interface 46.
- a high-pressure hydraulic pump 12 is mounted to the rear side of the engine front cover 14.
- the high-pressure hydraulic pump 12 supplies hydraulic-actuating fluid, preferably lubricating oil, to the fuel injectors.
- the hydraulic pump is driven by a gear train (not shown) located within the front cover 14.
- the front cover or lower portion 14 forms a lower reservoir 16 defined by a lower front wall 18, lower side walls 19, a lower rear wall 20, and a bottom wall 22.
- the front cover 14 is made of cast iron. However, other suitable materials and forming methods may be used.
- the front cover 14 has a top edge forming a lower opening at interface 46. The top edge has a depression 44.
- a lower reservoir supply passage 26 is cast as part of the front cover 14.
- the lower reservoir supply passage 26 is even with the top edge of the front cover 14.
- the depression 44 surrounds the lower reservoir supply passage 26 along the top edge.
- the lower reservoir supply passage 26 connects to the engine lubricating oil pump (not shown).
- the engine-lubricating pump supplies lubricating oil to the reservoir and hydraulic pump 12.
- the upper reservoir structure 30 is mounted on the front cover 14 at the interface 46.
- the upper reservoir structure 30 forms an upper reservoir 35 defined by upper front wall 32, upper sidewalls 33, an upper rear wall 34, and an access cover 36.
- the upper reservoir 35 is larger than the lower reservoir 16.
- the upper reservoir structure 30 is made from cast iron. However, other materials and forming methods made be used.
- the upper reservoir structure 30 has a bottom edge forming an upper opening at interface 46.
- An upper reservoir supply passage 28 is cast as part of the upper reservoir structure 30.
- the upper reservoir supply passage 28 is even with the bottom edge and terminates adjacent to the access cover 36.
- the upper reservoir supply passage has an outlet 40, which opens to the upper reservoir 35.
- the upper reservoir structure 30 When the upper reservoir structure 30 is mounted on the front cover 14 at interface 46, the upper front wall 32 meets lower front wall 18.
- the upper sidewalls 33 meet the lower sidewalls 19.
- the upper rear wall 34 meets the lower rear wall 20.
- the upper reservoir supply passage 28 mates with the lower reservoir supply passage 26 to form one continuous reservoir supply passage.
- the upper opening meets the lower opening to form a priming reservoir along the inner periphery of the upper reservoir structure 30 and front cover 14.
- the priming reservoir permits fluid communication between the upper and lower reservoirs.
- a passage 24 Adjacent to the bottom wall 22, a passage 24 intersects the reservoir portion 16.
- the passage 24 connects to a fluid supply inlet (not shown) of the hydraulic pump 12.
- an air bleed and overflow drain passage 27 extends between the upper reservoir structure 30 and the front cover 14 as partially shown FIG. 2.
- the depression 44 surrounds the air bleed and overflow drain passage 27 along the top edge.
- a filter gasket 50 seals the interface 46 between the front cover 14 and the upper reservoir structure 30.
- the filter gasket 50 includes a gasket 42 and a screen assembly 70.
- the gasket 42 is preferably silicone rubber, but it may be made from another suitable sealant materials.
- the gasket 42 has an elongated circular cross section for disposing in the depression 44.
- the gasket 42 surrounds the entire periphery of the interface 46, the reservoir supply passage 26, 28, and the air bleed and overflow drain passage 27. As shown in FIG. 4, the gasket 42 has a reservoir gasket portion 54 surrounding the periphery of the reservoir.
- the screen assembly 70 has a filter screen 76 connected to a plate member 56.
- the filter screen 76 is cylindrical and has an open end 72 and a closed end 78.
- the cylindrical shape has a large surface area for trapping debris.
- Filter screen 76 may be another shape including conic, rectangular, and flat.
- the open end 72 preferably faces the direction of the fluid flow.
- closed end 78 preferably faces the direction of the fluid flow. The orientation of the screen reduces the adverse effects of debris build-up on the screen. For example, if the open end of a cone-shaped filter screen faces the direction of the fluid flow, the build-up of debris at the tip of the cone blocks the mesh on both sides of the screen.
- Filter screen 76 has a mesh size based on the particle size to be excluded. The finer the mesh size, the more debris retained by the filter screen 76. However, it is not necessary to retain all particles in the hydraulic fluid. Some particles are small enough to flow through the small orifices of the control valves and other engine parts without getting stuck. A screen with a 140 micron mesh size retains the larger, dangerous particles while permitting the smaller, inconsequential particles to pass.
- the mesh size and the desired pressure drop across the screen determine the open area of filter screen 76.
- a pressure drop of less than 5 psi is desired for proper operation of the high pressure pump 12.
- the desired pressure drop may require a screen with a large surface area, i.e. open area. Consequently, the filter screen 76 may need a cylindrical, conic, or some other non-flat shape in order to fit within the reservoir.
- the reservoir may be reconfigured so a flat screen with sufficient surface and open areas could be used to provide the desired pressure drop.
- the plate member 56 has a solid, planar structure. It is configured to extend beyond the periphery of the reservoir and contact the reservoir gasket portion 54.
- the plate member 56 forms an aperture 62. While different shapes and dimensions may be used, aperture 62 has essentially the same shape and inside dimensions as the filter screen 76.
- a flange 66 may be used to connect the filter screen 76 to the plate member 56. If no flange is used, the filter screen 76 connects directly to the plate member 56. If a flange is used, the plate member 56 preferably forms the flange 66 along the peripheral edge of aperture 62.
- the flange 66 also may be a separate attachment to the plate member 56. Flange 66 enables a solid weld or other connection between the filter screen 76 and plate member 56. Accordingly, the plate member 56 forms a barrier between the lower reservoir 16 and the upper reservoir 35, forcing fluid communication through the filter screen 76.
- the plate member 56 forms a basket assembly 80 for holding and supporting the filter screen 76 as shown in FIG. 8.
- the basket assembly 80 has support arms 82 and a support ring 84.
- the support arms 82 and the support ring 84 mechanically support the filter screen 76.
- the filter screen 76 may be attached to the basket assembly 80.
- the plate member 56 and the filter screen 76 may be made from steel, aluminum, plastic, other materials, or a combination.
- the plate member 56 is made from black-oxide coated, carbon steel plate.
- the filter screen 76 is made from stainless steel and is welded to the flange 66 formed on the plate member 56.
- the basket assembly 80 is made from the black-oxide coated, carbon steel plate. The stainless steel screen may be welded to the basket assembly 80.
- the plate member 56 and the filter screen 76 are made of plastic.
- plastic it is preferable to have the basket assembly 80 as part of the plate member 56.
- the plastic screen may be integrally formed with the plate member 56 and basket assembly 80 when they are molded from the plastic.
- the plate member 56 and the basket assembly 80 may be a single part.
- the plate member 56 is integrally incorporated into the reservoir gasket portion 54 as shown in FIG. 4.
- a plurality of bonding holes 58 are disposed adjacent to and along the periphery of plate member 56.
- plate member 56 is positioned inside an injection mold so the gasket material forms the reservoir gasket portion 54 along the periphery of plate member 56.
- the material used to make gasket 42 essentially fills the bonding holes 58.
- the material in the bonding holes 58 remains in contact with and is part of the gasket 42.
- the gasket 42 is mechanically bonded to the plate member 56.
- the plate member has a locating bump 60 for positioning the plate member 56 in the injection mold.
- the edges of plate member 56 may be coated with a bonding agent to chemically bond the reservoir gasket portion 54 to the plate member 56.
- the plate member 56 avoids these problems. It enables the filter gasket 50 to be a single part having the filter screen 76 integrally-connected to the gasket 42. The plate member 56 also separates the upper and lower portions 16, 35. Consequently, it forces the hydraulic fluid to flow through the filter screen 76.
- the plate member 56 is not integrally formed with the reservoir gasket portion 54 as shown in FIGS. 9-10.
- the screen assembly 70 and the gasket 42 are separate pieces. Consequently, there is no need for the bonding holes 58 and the locating bump 60 on the plate member 56.
- the screen assembly is placed into the opening for the lower reservoir 16.
- the periphery of the plate member 56 extends beyond the periphery of the lower reservoir 16 and rests on the top edge of the front cover 14.
- the loose gasket 42 is positioned in the depression 44.
- the upper reservoir structure 30 is mounted on the front cover 14 sealing the gasket 42 against the plate member 56.
- the plate member 56 forms a barrier between the lower reservoir 16 and the upper reservoir 35, thus forcing fluid communication through the filter screen 76.
- the filter gasket 50 provides a further advantage when the plate member 56 is integrally-attached to the reservoir gasket portion 54.
- the integrally-attached filter gasket makes it impossible to build the engine or system without the filter screen and pass a leak check test. If the filter screen 76 is omitted, there will be a noticeable leak from the missing gasket 42.
- the location of the filter gasket 50 takes advantage of the natural break between the upper reservoir structure 30 and the front cover 14.
- the filter gasket 50 could be applied in other locations. These locations include other natural breaks between parts forming the reservoir, other natural breaks between parts forming the hydraulic system, and even places where there are no natural breaks between the parts.
- the filter gasket may be placed between the top of the reservoir and its cover.
- the supply to the reservoir needs to enter through the cover.
- the supply could enter an outlet located in the space between the filter gasket and the cover.
- the filter gasket 50 may be positioned in places where there is not a natural break between the parts. In these locations, the filter gasket will need some means to hold it in position.
- the gasket 42 may not be necessary in these locations depending on the means used to hold the filter screen in place. However, the filter still must separate the reservoir or hydraulic section to force the hydraulic fluid through the screen.
